Abstract

COMPRESSOR LINEAR. A presente invenção divulga um compressor linear no qual um pistão (6) é acionado por um motor linear (10) e alternado linearmente do lado de dentro de um cilindro (4) para succionar, comprimir e descarregar refrigerantes. O compressor linear sincroniza a freqüência de operação do motor linear (10) com a freqüência natural do pistão (6), considerando que a força elástica da mola mecânica (8a, 8b) e da mola a gás que suporta elasticamente o pistão (6) na direção de movimento varia pelo carregamento. Mesmo se o carregamento variar, o motor linear é operado no estado de ressonância, para maximizar a eficiência. O compressor linear varia o curso do pistão (6) de acordo com o carregamento, desse modo lidando ativamente e superando rapidamente o carregamento e reduzindo o consumo de energia.LINEAR COMPRESSOR. The present invention discloses a linear compressor in which a piston (6) is driven by a linear motor (10) and linearly alternated inside a cylinder (4) to suction, compress and discharge refrigerants. The linear compressor synchronizes the operating frequency of the linear motor (10) with the natural frequency of the piston (6), whereas the tensile force of the mechanical spring (8a, 8b) and the gas spring that elastically supports the piston (6) The direction of movement varies by loading. Even if loading varies, the linear motor is operated in resonance state to maximize efficiency. The linear compressor varies the stroke of the piston (6) according to the loading, thereby actively dealing with and quickly overcoming the loading and reducing energy consumption.
